On one list layout, I have a 5 fields. It is possible created a just one script for sorting ascending/descending for all 5 fields?

Use Getfield() function. It will help you to do whate you want.

Or use script parameters to branch in one sort script.

I think that catch is in script parameter, but how to add a script parameter in sort step, when there isn't a calculation? In sort step You must specify a field for sorting.

Use a global for remembering the last sort, and a script parameter to know what the selected sort is on:

If [ Get(ScriptParameter) = "Name" ]

  If [ gLastSort = "Name Ascending" ]

    Sort [ Restore ; by Name (Decending) ]

    Set Field [ gLastSort ; "Name Decending" ]

  Else

    Sort [ Restore ; by Name (Ascending) ]

    Set Field [ gLastSort ; "Name Ascending" ]

  End If

Else If [ Get(ScriptParameter) = "Date" ]

  If [ gLastSort = "Date Ascending" ]

    Sort [ Restore ; by Date (Decending) ]

...

[color:"green"] Use a global for remembering the last sort

Yes, that is right.

[color:"green"]

If [ Get(ScriptParameter) = "Name" ]

  If [ gLastSort = "Name Ascending" ]

    Sort [ Restore ; by Name (Decending) ]

    Set Field [ gLastSort ; "Name Decending" ]

  Else

    Sort [ Restore ; by Name (Ascending) ]

    Set Field [ gLastSort ; "Name Ascending" ]

  End If

Else If [ Get(ScriptParameter) = "Date" ]

  If [ gLastSort = "Date Ascending" ]

    Sort [ Restore ; by Date (Decending) ]

...

That solution is OK for one layout. But my application contain almost 50 layouts, and will be very useful to create a dynamic system, one dynamic script for all possibly fields.

Something like.... that You shouldn't precise what field is sorting (e.g. "by Date")in script step:

Sort [ Restore ; by Date (Decending) ]

If can, on some way script parameter do that.... On that way created script can be useful in every future application.

In that case, look into doing it with GetField(). I posted a sample of this a couple months back. In was in a thread about 'dynamic reports' or 'dynamic portals'.

Hi,

Yes, GetField is the way to go as a start, but could get a bit more complex if the fields format could vary, from Time, Date, Number ot Text.

I've posted a demo in the Samples Forums to account for these cases.

The demo use a portal but can be used with lists as well.

Sorry but I can't find your posted sample. Can You give me a link, please?

Here it is, right where I left it.

But listen to Ugo too. My basic demo would not handle sorting dates and numbers properly.

Thanx Ugo,

I'll get back later with my impressions. First I must read Your calc. field very patiently; it's complicated for my skill of filemaker. I hope that will help me.

Thanx man, You are VERY fast. :-)

Hi again,

Thanks everybody for help!

I attached my solution for dynamic sort here, and on post in Sample files too.

My solution required that every layout have a three extra fields ( text, number and date). They are a temporary fields in which values are copied from desired sort column fields.

Now, I have another question. Loop is very slow for thousands records; how can be faster? UGO sent a file RandomCreation few days ago, but unfortunately I can understand it. Can You please, give some extra instruction for using Your faster loop solution?

TIA
